The input levels and difference voltage provide no noise immunity and should be tested only in a static, noise-free environment.
This parameter is listed using a magnitude and polarity/direction convention, rather than an algebraic convention, to match the original
Agere data sheet.
Test must be performed one lead at a time to prevent damage to the device.

Parameters t
and t
are measured from the 1.5 V point of the input to the crossover point of the outputs (see Figure 2).
t
is the magnitude of the difference in propagation delay times between any specified outputs of two devices when both devices
operate with the same supply voltage, at the same temperature, and have identical packages and test circuits.
